Calibrachoa plant named ‘CCZYE01-0’

ABSTRACT

A new and distinct  Calibrachoa  cultivar named ‘CCZYE01-0’ is disclosed, characterized by large flower size and distinctive bright yellow flower color. The new variety is a  Calibrachoa , normally produced as an ornamental outdoor garden or container plant.

Latin name of the genus and species: Calibrachoa sp.

Variety denomination: ‘CCZYE01-0’.

BACKGROUND OF THE INVENTION

The new Calibrachoa cultivar is a product of a planned breeding programconducted by the inventor, Jun Tsukahara in Yame, Fukuoka, Japan. Theobjective of the breeding program was to produce new Calibrachoavarieties for commercial ornamental applications. The cross resulting inthis new variety was made during September 2007.

The seed parent is an unpatented, unnamed proprietary seedling varietyof Calibrachoa, with a pale greenish yellow flower. The pollen parent isan unpatented, unnamed proprietary seedling variety of Calibrachoa, witha dark red flower. The new variety was discovered in May, 2008 by theinventor in a group of seedlings resulting from the 2007 crossing, in aresearch greenhouse in Yame, Fukuoka, Japan.

Asexual reproduction of the new cultivar ‘CCZYE01-0’ by tissue culturewas first performed at a research greenhouse in Yame, Fukuoka, Japan inMay, 2008. Subsequently, the new variety has been propagated byvegetative cuttings, and has shown that the unique features of thiscultivar are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The cultivar ‘CCZYE01-0’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘CCZYE01-0’. These characteristics incombination distinguish ‘CCZYE01-0’ as a new and distinct Calibrachoacultivar:

-   -   1. Large flower size    -   2. Unique bright yellow flower color

PARENT COMPARISON

Plants of the new cultivar ‘CCZYE01-0’ are similar to plants of the seedparent, an unnamed proprietary seedling variety of Calibrachoa, with apale greenish yellow flower, in most horticultural characteristics.However, plants of the new cultivar ‘CCZYE01-0’ produce larger flowersof a different color, as well as longer stems and narrower leaves.

Plants of the new cultivar ‘CCZYE01-0’ are similar to the plants of thepollen parent, an unpatented, unnamed proprietary seedling variety ofCalibrachoa, with a dark red flower in most horticulturalcharacteristics. However plants of the new cultivar ‘CCZYE01-0’ producelarger flowers of a different color, as well as shorter stems and widerleaves.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘CCZYE01-0’ are best compared to the varietyCalibrachoa ‘SUNbelki’, U.S. Plant Pat. No. 11,558. The two Calibrachoavarieties are similar in most horticultural characteristics, however,the new variety ‘CCZYE01-0’ differs in having an overall brighter yellowflower color and brighter yellow flower center.
